PUMP.

. Specification of Letters Patent To all whom it may concern.' i

Be it known that I, JESSE REED, of Marshfield, in the county of Plymouth and Commonwealth of Massachusetts, machinist, have invented, constructed, made, and applied to use a new and useful Improvement in the Construction of Pumps, the annexed drawings of which herein referredto, t0- gether with the following description, form my specification. j

The improvements I contemplate requlre a substitution of parts not ordinaril employed in working pumps, and a di erent I dispense with the boxes in common use that contain the valves and also with the piston rod, and instead of them I employ and use a movable valve plate with parts adapted to lts application. j v.

To distinguish this pump from others 1n use I shall designate it by the name of The Franklin Pump.

.Although other forms than the one I have adopted will answer, yet I prefer the one hereinafter described.

Figure A and Fig. B of the accompanying ldrawing represent my improvement, the

first being a side view and the second a cross section. The body of the ump a, Figs. A,L B, is about twelve inches ong, nine inches wide one way, and six inches the other, or may be of other suitable dimensions. It may be made of wood although metal is much preferable. The top end is open and a little flaring. The interior surface Z, m, Fig. B, should be made smooth against which the v edge of the valve plate rubs. Through the bottom is an aperture C, Fig. B, to admit the water, over which I place the lower valve b and secure it in blace by means of a leather hinge n, and an oblong block of wood rf reposing on the bottom, and at pne side of the pump, which I call the side-piece and which is kept in place by a wedge o. An arm d, about two inches long, either perpendicular or oblique, projects from the upper surface of this valve, by means of which the valve maygbe opened to let oi' the water to prevent its `freezingin severe weather; but having described this ina former specication I do not now claim it as being new.

N, Fig. A, represents the nose of the pump. The valve plate D, is stationed No. 853, dated July 24, 1838.

f within the pump. LItS thickness is about a quarterof an inch.V Its length and width correspond on threesides with the interior circumference of the pump and the other side or edge in conjunction with theishelf E described below forms the hinge on which it works. To facilitate the packing which is by means of a strip of leather, one edge a little eleva-ted, I cast around the sides or edges of said plate an angular lip P, or elevation three eighths of an inch high, to which I rivet or otherwise fasten the leather z'. Near its center is an aperture 7' to admit the water as the brake s is-raised. Upon the uppersurface directly over Said aperture r I placethe upper valvee, which also is kept in place by a leather hinge attached at one end to said plate. f The hinge E of the valve plate is` constructed zas follows,

viz: `At one side of said pump within, about three inches from the bottom, 1I fix ga horizontal shelf t, about Vtwo inches wide with a semi circular channel or groove on its projecting edge, and on one edge l of the valve plate -Icast a cylindrical arbor f of like diameter with that'ofpthe groove on the edge of the shelf, and being. suitably fitted together the former within the i latter a correct movement againstanymliability to looseness by wear is preserved, and fa strong durable hinge within thepump is formed.

The shelf is fastened to the sideof the j pump by a screw' z" through the pump and as an additional support to the shelf IV cast two, knobs u upon the inside .of the pump just beneath the hinge. "The pump,

brake s is sobent as to admit of putting one end into the top lof the pump so as to reach the valve plate D, to which it is firmly screwed, and when its outer endis elevated, the valve plate descends turning on its hinge and the valve on its upper surface4 rises. VWhenfthe front edge of the valve plate rubs against the side of the pump a slight curve is made in the latter, corre` Vspending with the `sweep of the former, to give to the plate-an easy motion and. effect.

The water from the fountain is conducted to the pump through a pipe fr,V Figs. A, B. I give preference to a lead pipe, one end of which is to be attached to the pump in any convenient manner.v i

The facility with which both valves may be taken out, cleaned and replaced When intervening part Aand in lieu-'of the common boX and piston rod. f

In testimony that the foregoing, together with the drawings hereto referredto, is a true specification of my said improvements, I do hereunto set my hand thissixteenth day of June in the year of our Lord Eighteen 20` hundred and thirty eight.y
